I’ve found the solution

I use

dialog.setCanceledOnTouchOutside(false);
dialog.setCancelable(false);

public class getcatogry extends AsyncTask<String, Void, Void> {

    private final ProgressDialog dialog = new ProgressDialog(
            MainActivity.this);

    // can use UI thread here
    protected void onPreExecute() {
        this.dialog.setMessage("Loading...");
        this.dialog.show();
        dialog.setCanceledOnTouchOutside(false);
        dialog.setCancelable(false);
    }

    // automatically done on worker thread (separate from UI thread)
    protected Void doInBackground(final String... args) {
        dialog.setCanceledOnTouchOutside(false);
        dialog.setCancelable(false);






        return null;
    }

    // can use UI thread here
    protected void onPostExecute(final Void unused) {
        if (this.dialog.isShowing()) {
            this.dialog.dismiss();




        }
        // reset the output view by retrieving the new data
        // (note, this is a naive example, in the real world it might make
        // sense
        // to have a cache of the data and just append to what is already
        // there, or such
        // in order to cut down on expensive database operations)
        // new SelectDataTask().execute();
    }
}

This way the async task will not get canceled even on back press or on touch async task
